The present disclosure relates to a compound of formula (I)
wherein:
A is an optionally substituted monocyclic or polycyclic aryl or heteroaryl group; B is an optionally substituted monocyclic nitrogen-containing heteroaryl group; and either a) R
1
and R
2
are chosen from a hydrogen atom and specified substituents, or b) R
2
, R
1
and the —NH— group to which R
1
is attached, form a moiety chosen from the moiety of formulae (IIa) and (IIb):
or a pharmaceutically acceptable salt thereof, or a N-oxide thereof. The present disclosure also relates to a method for treating a subject afflicted with a pathological condition or disease susceptible to amelioration by antagonism of the A
2B
adenosine receptor.

The present invention provides a compound of formula (I) wherein: A represents an optionally substituted monocyclic or polycyclic aryl or heteroaryl group B represents an optionally substituted monocyclic nitrogen-containing heteroaryl group; and either a) R
1
and R
2
represent hydrogen or specified substituents, or b) R
2
, R
1
and the —NH— group to which R
1
is attached, form a moiety selected from the moiety of formulae (IIa) and (IIb): (IIa) These compounds are useful as antagonists of the A2B receptor, for instance in the treatment of asthma.
Aminopyrazine compounds as modulators of an adenosine receptor are provided. The compounds may find use as therapeutic agents for the treatment of diseases mediated through a G-protein-coupled receptor signaling pathway and may find particular use in oncology.
